Honeywell zone valve replacement questions

I want to replace two honeywell zone valves:

One is model v8043E1012 the other is older than that. The V8043's motor is sticking but when I remove the cover and give it a spin it kicks in so I'm not sure if it is the motor or a stuck valve. Let me know what you think.

The motor on the older valve is dead so I want to replace the whole set up. My question is I have 1/2 pipe leading into the 3/4 valve opening and I'm not sure how to solder that connection. Is there a reducer I need to buy?

Here are some pics and thanks for the advice.

Pics didn't post...

Set up a FREE account at Image hosting, free photo sharing & video sharing at Photobucket and upload the pics to a PUBLIC album. Come back here and post a link to your album.

[edit: I'm not sure why your pics don't show... I see you have them on a hosting site... standby, let me check something out...]

There are OLD and NEW varieties of the Honeywell valves. Are BOTH valves Honeywell?

You don't need to replace the whole valve. You can just replace the power head assembly. If you have the OLD variety of valve, you will need an 'adapter kit' to install a new head, and you will have to drain the water in order to do so. The NEWER valves don't require draining the system.

Let's see the pics first and go from there...

Apparently you need to insert those links as URL, not IMG... don't know why...

Take some more pics... pull back with the camera and let's see a wider angle.

You can tell the old from the new by the number of screws that hold the head to the valve.

The OLD series have FOUR screws attaching the head to the body, and these can NOT be changed without draining the system.

The NEW series have TWO screws, diagonally opposite, and two 'locating pins' at the other two locations. These CAN be changed without draining.
